Merge tag 'mmc-merge-for-3.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc

Pull MMC updates from Chris Ball:

Core:
 * Support for MMC 4.5 Data Tag feature -- we tag REQ_META, so devices
   that support Data Tag will provide increased throughput for metadata.
 * Faster detection of card removal on I/O errors.

Drivers:
 * dw_mmc now supports eMMC Power Off Notify, has PCI support, and
   implements pre_req and post_req for asynchronous requests.
 * omap_hsmmc now supports device tree.
 * esdhc now has power management support.
 * sdhci-tegra now supports Tegra30 devices.
 * sdhci-spear now supports hibernation.
 * tmio_mmc now supports using a GPIO for card detection.
 * Intel PCH now supports 8-bit bus transfers.

+* TI Highspeed MMC host controller for OMAP
+
+The Highspeed MMC Host Controller on TI OMAP family
+provides an interface for MMC, SD, and SDIO types of memory cards.
+
+Required properties:
+- compatible:
+ Should be "ti,omap2-hsmmc", for OMAP2 controllers
+ Should be "ti,omap3-hsmmc", for OMAP3 controllers
+ Should be "ti,omap4-hsmmc", for OMAP4 controllers
+- ti,hwmods: Must be "mmc<n>", n is controller instance starting 1
+- reg : should contain hsmmc registers location and length
+
+Optional properties:
+ti,dual-volt: boolean, supports dual voltage cards
+<supply-name>-supply: phandle to the regulator device tree node
+"supply-name" examples are "vmmc", "vmmc_aux" etc
+ti,bus-width: Number of data lines, default assumed is 1 if the property is missing.
+cd-gpios: GPIOs for card detection
+wp-gpios: GPIOs for write protection
+ti,non-removable: non-removable slot (like eMMC)
+ti,needs-special-reset: Requires a special softreset sequence
+
+Example:
+	mmc1: mmc@0x4809c000 {
+		compatible = "ti,omap4-hsmmc";
+		reg = <0x4809c000 0x400>;
+		ti,hwmods = "mmc1";
+		ti,dual-volt;
+		ti,bus-width = <4>;
+		vmmc-supply = <&vmmc>; /* phandle to regulator node */
+		ti,non-removable;
+	};
